I’ve done a similar test….. no difference ! Ughhhhh
I have a decently resolving system :
Wilson wp6 speakers
pass labs xa 25 amp
Lampizator golden atlantic dac
Lumin u2 mini, node 2, Mac mini
Preamps Benchmark hpa4 and Prima Luna dialogue w new tubes
I am starting to believe all of these fancy reviewers on YouTube are completely biased in their reviews. I love how they wax poetic about this dac versus this streamer, and in the end, not much difference when I listen . Whenever one of them says the difference is minimal, I know what that really means, the difference isn’t there. I have spent way too much money trying different fancy gear only to find minimal difference. Even fancy Dacs are surprisingly close. My lampi certainly does not destroy my cheap topping dac. But, I can hear a difference and I can pick it out in a blind direct AB test every time. Put me in a room and ask me which dac is playing, not so easy.
good stuff!
